Behold a curious tale of Floridian retirees, golf courses, and a crumbling reality: The Villages, the world's largest retirement community in Central Florida, sees an alarming increase in sinkholes due to its accelerated development and the state's limestone bedrock which dissolves, creating underground cavities resulting in sinking terrain, commonly known as "karst." Though Florida may resemble a slice of Swiss cheese, fear not, for it doesn't hold the dubious honor of having the most sinkholes in the US.
